The Space Anomaly is a large round, metallic structure in No Man's Sky. It can be found in random solar systems, near the Space Station. It can also be summoned from the Starship quick menu while in space.
Approaching the doors of a Space Anomaly will automatically guide a Starship inside, in the same way that a Space Station does. Priest Entity Nada and Specialist Polo are always found within the Space Anomaly.
It has now become a player hub to gain easy quicksilver and quests. it also helps with technology.
